Notes:

Part numbers are for reference only. Alternate components may be substituted.

It's also possible to run the RF2126 at around 6.5 volts for slightly more power output. You could try a 7805 voltage regulator with two silicon diodes (or a red LED) in series with the ground lead (cathode to ground).

Be sure to isolate the ground tab on the 7805 though or it won't work. You can even just use a plain old 7806 voltage regulator for 6 volts output.
